NUF4000MU

4-Channel EMI Filter with

Integrated ESD Protection

The NUF4000MU is a four−channel (C−R−C) Pi−style EMI filter

array with integrated ESD protection. Its typical component values of

R = 100

W and C = 15 pF deliver a cutoff frequency of 105 MHz and

stop band attenuation greater than −30 dB from 800 MHz to 5.0 GHz.

This performance makes the part ideal for parallel interfaces with

data rates up to 70 Mbps in applications where wireless interference

must be minimized. The specified attenuation range is very effective

in minimizing interference from 2G/3G, GPS, Bluetooth

® and

WLAN signals.

The NUF4000MU is available in the low−profile 8−lead 1.2x1.8mm

UDFN8 surface mount package.
